这周做了一个来电知了的项目，具体需求如下：
1.可以设置黑名单号码，拒接电话和短信
2.来电归属地查询
在生活中我们用到这些东西的时候感觉挺简单，但是让我们实现这些功能时，还是非常麻烦的。下面是我在做这个项目时的实现过程。
<一>设计首页，显示黑名单号码，并能进行黑名单添加和删除及其归属地查询功能。具体代码如下：
main.xml：主界面的布局文件
1. <?xml version="1.0" encoding="utf-8"?>
2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3. android:orientation="vertical"
4. android:layout_width="fill_parent"
5. android:layout_height="fill_parent"
6. android:background="#8A2BE2">
7. <TextView
8. android:layout_height="wrap_content"
9. android:layout_width="fill_parent"
10. android:text="黑名单号码"
11. android:id="@+id/tv_blacknumber"
12. android:gravity="center"
13. android:textColor="#ff0000"
14. android:textSize="25px"/>
15. <ListView
16. android:layout_width="fill_parent"
17. android:layout_height="wrap_content"
18. android:id="@android:id/list"
19. android:cacheColorHint="#00000000"
20. android:layout_weight="1"/>
21. <TextView
22. android:id="@android:id/empty"
23. android:layout_width="fill_parent"
24. android:layout_height="fill_parent"
25. android:text="无黑名单号码，请添加!"
26. android:gravity="center"
27. android:textColor="#00CD00"
28. android:textSize="25px"
29. android:layout_weight="1"/>
30. <LinearLayout android:id="@+id/ll_bottom"
31. android:orientation="horizontal"
32. android:layout_width="fill_parent"
33. android:layout_height="wrap_content"
34. android:background="@drawable/buttonbackground">
35. <Button android:id="@+id/btn_add"
36. android:layout_width="wrap_content"
37. android:layout_height="fill_parent"
38. android:layout_weight="1"
39. android:background="@drawable/button_selector"
40. android:text="添 加"/>
41. <Button android:id="@+id/btn_search"
42. android:layout_width="wrap_content"
43. android:layout_height="fill_parent"
44. android:layout_weight="1"
45. android:background="@drawable/button_selector"
46. android:text="归属地查询"/>
47. <Button android:id="@+id/btn_delete"
48. android:layout_width="wrap_content"
49. android:layout_height="fill_parent"
50. android:layout_weight="1"
51. android:background="@drawable/button_selector"
52. android:text="删 除"/>
53. <CheckBox android:id="@+id/cb_select_all"
54. android:layout_width="wrap_content"
55. android:layout_height="fill_parent"
56. android:layout_weight="1"
57. android:text="全 选"/>
58. </LinearLayout>
59. </LinearLayout>
这里我为BUTTON按键设置了一个背景色。代码如下：
button_selector.xml：
1 <?xml version="1.0" encoding="utf-8"?>
2 <selector
3 xmlns:android="http://schemas.android.com/apk/res/android">
4 <item android:state_pressed="true" > <!-- 被按下的情况下 -->
5 <shape>
6 <!-- 渐变 -->
7 <gradient
8 android:startColor="#99FFFF"
9 android:endColor="#33FF00"
10 android:type="linear"
11 android:angle="270"/>
12 <!-- 描边 -->
13 <stroke
14 android:width="2dp"
15 android:color="#CCCC00"
16 android:dashWidth="5dp"
17 android:dashGap="3dp" />

27 </shape>
28 </item>
29
30 <item android:state_focused="true" > <!-- 获得焦点的情况下 -->

32 <gradient

36 <stroke
37 android:width="2dp"
38 android:color="#00FFFF" />
39 <corners

41
42 <padding

44 android:top="5dp"
45 android:right="5dp"
46 android:bottom="5dp" />
47 </shape>
48 </item>
49
50 <item> <!-- 一般情况下 -->
51 <shape>
52 <solid android:color="#FFFACD"/>
53 <stroke
54 android:width="4dp"
55 android:color="#00FFFF" />
56 <corners
57 android:topRightRadius="5dp"
58 android:bottomLeftRadius="5dp"
59 android:topLeftRadius="5dp"

61 <padding

63 android:top="5dp"
64 android:right="5dp"
65 android:bottom="5dp" />
66 </shape>
67 </item>
68 </selector>
ListView的设计：
blacknumber_list_item.xml：
1. <?xml version="1.0" encoding="utf-8"?>
2. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
3. android:orientation="horizontal"
4. android:layout_width="fill_parent"
5. android:layout_height="fill_parent">
6. <TextView android:id="@+id/tv_item_number"
7. android:layout_width="wrap_content"
8. android:layout_height="40dip"
9. android:gravity="center"
10. android:textSize="20sp"
11. android:textColor="@drawable/itemcolor"
12. android:layout_weight="1"
13. android:layout_marginRight="6dip" />
14. <CheckBox
15. android:id="@+id/cb_item_delete"
16. android:layout_width="wrap_content"
17. android:layout_height="40dip"
18. android:layout_weight="1"
19. android:focusable="false"
20. android:checked="false"
21. android:clickable="false"
22. android:layout_alignParentRight="true"
23. android:layout_marginLeft="2dip"/>
24. </RelativeLayout>

<二>由于要对黑名单进行增删查操作，多归属地要进行查操作，所以我们需要创建一个数据库帮助类，还有就是要将数据库拷到应用文件目录下。下面就将实现代码附在下面，大家自己琢磨吧。
